Multiaxial cyclic behaviour and fatigue modelling of AM30 Mg alloy extrusion

CORROSION BEHAVIOUR OF Al-Li-Cu-Mg ALLOY 8090-T651

Microstructure Modelling of Hot Deformation of Al-1%Mg Alloy

This study presents the application of the finite element method and intelligent systems techniques to the prediction of microstructural mapping for aluminium alloys. Here, the material within each finite element is defined using a hybrid model. The hybrid model is based on neuro-fuzzy and physically based components and it has been combined with the finite element technique. The model simulate...

Multiaxial fatigue reliability analysis of railroad wheels

A general methodology for fatigue reliability degradation of railroad wheels is proposed in this paper. Both fatigue crack initiation and crack propagation life are included in the proposed methodology using previously developed multiaxial fatigue models by the same authors. A response surface method in conjunction with design of experiments is used to develop a closed form approximation of the...

Wear Behavior and Microstructure of Mg-Sn Alloy Processed by Equal Channel Angular Extrusion

Mg-5wt.% Sn alloy is often used in portable electronic devices and automobiles. In this study, mechanical properties of Mg-5wt.% Sn alloy processed by Equal Channel Angular Extrusion (ECAE) were characterized. More precisely, its hardness and wear behavior were measured using Vickers hardness test and a pin-on-disc wear test. The microstructures of ECAE-processed Mg-Sn alloys were investigated ...

Dislocation Substructure Evolution during Hydrostatic Extrusion of Al Mg Si Alloy

Hydrostatic extrusion is a technique which allows to produce rods with ultra ne grains and unexpectedly enhanced mechanical properties caused by grain re nement. However, the mechanism of such a re nement is not fully understood at this stage. 6xxx aluminium alloys series are usually processed by extrusion. In this study, commercial 6082 aluminium alloy was extruded at ambient temperature in a ...
